Creeping Thistle - Cirsium arvense
Medium to tall stoloniferous plant, stem usually branched, but not winged or spiny. Leaves lanceolate to oblong, pinnately lobed or unlobed, spiny, the upper leaves unstalked. Flowerheads pale purple or lilac, 15 to 25 mm, fragrant, solitary or from 2 to 5 together, stalked.
Lighter pink that most other thistles, and stem not winged, or with very short wings. As with all Cirsium, the pappus-hairs (the silky white hairs attached to the seed - the thistledown) are individually feathery or branched.
Meadows, arable land, roadsides and waste places.
June to September.
Perennial.
Very common throughout Britain.
Very common in Leicestershire and Rutland. In the 1979 Flora survey of Leicestershire it was found in 606 of the 617 tetrads.

Uroleucon aeneum
The adult Uroleucon aeneum apterae has a body length of is 3.0 to 4.3 mm. The cauda (tail) in this species is black which helps to identify it. It is associated with Thistles.
Large Thistle Aphid
The Large Thistle Aphid (Uroleucon cirsii) is found on Thistles, especially Creeping Thistle. It is between 4 and 5.2 mm in length and has characteristic two tone legs. The cauda (tail) is pale dusky yellow in this species which helps to distinguish it from other thistle feeding aphids.
Chromatomyia autumnalis
The larva of the Agromyzid fly Chromatomyia autumnalis mines the leaves of various thistles such as Creeping Thistle and also some knapweeds. The mine is full depth, greenish, usually linear. It is usually upper surface and doubles back on itself. The pupa is metallic black and the anterior spiracles protrude through the lower epidermis. The mine can only be separated from that of Chromatomyia spinaciae by examining the puparium. The puparium of Chromatomyia spinaciae is white whereas Chromatomyia autumnalis is black.
Chromatomyia spinaciae
The larvae of the fly Chromatomyia spinaciae form long narrow greenish mines in the leaves of various thistles, and also in the leaves of Knapweed and Perennial Cornflower. The puparium is white and forms at the end of the mine, underneath the leaf. The frass grains are large and scattered. The leafmine of this species is identical to that of Chromatomyia autumnalis and can only be separated by the puparium features. The puparium of Chromatomyia spinaciae is white whereas that of Phytomyza autumnalis is black.
Phytomyza cirsii
The larva of the Agromyzid fly Phytomyza cirsii mines the leaves of various thistles (Cirsium) including Creeping Thistle and Spear Thistle, creating a long whitish upper surface mine. The frass grains are small and usually occur close together. Pupation is outside the mine. There are other very similar mines on these host species and care is needed when identifying the causer.
Thistle Gall Fly
The larva of the Thistle Gall Fly (Urophora cardui) causes distinctive swollen stem galls on Creeping Thistle. These are green and fleshy to begin with, and persist on old stems. Several chambers are inside. Adults fly in June, laying eggs on the thistle. The larvae hatch and crawl down into the stem, causing the gall.
Creeping Thistle Rust
This rust causes galls on Creeping Thistle, and the whole plant appears stunted. There is no host alternation. Sickly-smelling yellow spermogonia are followed by brown aecia covering the leaf underside; light brown uredinia and darker brown telia are present later.
